"Snowden dollars were struck as an anti-counterfeiting measure. The edge was struck from a novel three-part collar that produced raised edge lettering on the coin. Considerable experimentation went into the production of these pieces, and on June 12, 1885 Snowden and his staff succeeded in getting the mechanism to work at normal production speeds of 80 to 100 coins per minute. Snowden retired at the end of the year, and left placement of the raised lettering to his successor. Director Burchard left office around the same time, and no one remained in the Mint who had Snowden's insight, ability, or willingness to experiment to carry his project forward to completion. The tripartite collar was not used again until 1907 when Augustus Saint-Gaudens' double eagles went into production."
